Optimize resource allocation, promote upgrading, and improve the self-sufficiency rate of chemicals

in 2008, the self-sufficiency rate of synthetic resin in China was only 60%, and more than 70% of high-end petrochemical products such as butyl rubber were imported. For petrochemical enterprises, an important task of changing the development mode is to improve the satisfaction rate of high-end products to downstream industries

domestic high-end petrochemical products can not meet the demand, which reflects the lack of cutting-edge technology reserves and the achievement that the import rate of the whole industry reaches 70%, and some production technologies of high-end petrochemical products are controlled by others. Production technologies such as polycarbonate mainly rely on introduction, while the introduction of key technologies such as isoprene rubber is limited. Large scale and integration of complete sets of technical equipment such as million ton ethylene has not yet been localized. In view of these situations, we must strengthen the research and development of key and cutting-edge technologies and enhance the supporting capacity of independent innovation for industrial development. At the same time, we should seize the opportunity to optimize the allocation of resources, adjust the product structure, improve the proportion of medium and high-end products, and promote the upgrading of products. Case Western Reserve University will combine TPU materials with PLA materials and graphene oxide 6 The external environment such as temperature and humidity also affects the measurement of the instrument. The materials are mixed and printed to produce cell culture scaffolds with good mechanical properties, which can enhance the effective supply capacity and meet the requirements of economic and social development

in the investment of technological transformation, 4. Wide expansion of force value: with high-precision sensors, we should focus on supporting the development of high-end chemical products, so as to significantly improve the self-sufficiency rate of high-end petrochemical products, and strengthen and expand the high-end petrochemical industry. In particular, we should encourage the research and development of high-end petrochemical products with high added value, strong relevance, substitution for imports and filling the gap, and focus on the development of functional products and raw materials for the electronic information industry, such as polycarbonate, fluororesin, etc; Structural materials and products for the automotive machinery industry, such as automotive polypropylene resin, high-performance radial tires, etc; Differentiated and special products for light industry and textile industry, such as caprolactam, polyphenylene sulfide, etc; Special and high-end products for aerospace, such as large civil aviation tires, super absorbent resins, and new materials and products for energy-saving and environmental protection industries, such as polyurethane, environmental friendly coatings, etc

to meet the social demand for high-end petrochemical products, we need not only the efforts of enterprises, but also the government to do a good job in planning. The relevant person in charge of Nanjing municipal government recently said that while strengthening and optimizing basic chemicals such as oil refining and ethylene, and extending the industrial chain of crude oil processing, basic chemical raw materials, chemical intermediates, fine chemicals and polymer materials, the petrochemical industry in Nanjing will focus on the development of refined oil products, resin special materials, high-grade fibers, high-grade rubber, new energy, life science chemicals, etc., so as to promote the development of petrochemical industry to high-end. Such an idea is undoubtedly worth promoting
